This paper provides secure parameters for a classical McEliece encryption scheme based on quasi-dyadic generalized Srivastava codes, and successively converts the scheme to a CCA2-secure protocol in the random oracle model applying the Fujisaki-Okamoto transform.Abstract:
In this paper we present efficient implementations of McEliece variants using quasi-dyadic codes. We provide secure parameters for a classical McEliece encryption scheme based on quasi-dyadic generalized Srivastava codes, and successively convert our scheme to a CCA2-secure protocol in the random oracle model applying the Fujisaki-Okamoto transform. In contrast with all other CCA2-secure code-based cryptosystems that work in the random oracle model, our conversion does not require a constant weight encoding function. We present results for both 128-bit and 80-bit security level, and for the latter we also feature an implementation for an embedded device.read more

Secure Integration of Asymmetric and Symmetric Encryption Schemes
TL;DR: This paper shows a generic and simple conversion from weak asymmetric and symmetric encryption schemes into an asymmetric encryption scheme which is secure in a very strong sense -- indistinguishability against adaptive chosen-ciphertext attacks in the random oracle model.
